Steel Girder Bridges are deck bridges which are used for short and medium spans, for
highway bridges composite deck construction is generally used
unless the depth is very critical in which case half-through
girders or through trusses may be necessary.

The surface protection can be paint or hot-dip galvanized.

Bridge load capacity, width can be designed according to user's
requirements

Introduction

Bailey Bridge is a standard bridge equipment, adopted extensively
and the most popular in the world

1. High strength and big stiffness , relative to the concrete
bridge can be reduced trabecular high and self-respect2. Due to the steel isotropic, quality of a material is uniform and
modulus of elasticity, that make steel bridge in the working
condition and calculation compared with the assumption3. Steel bridge generally USES factory, site splicing, the
construction period is short, processing convenient and not
affected by seasonal effect.4. Steel bridge is suitable for industrialized manufacture and very
convenient to transport.5. Steel bridge is easy to repair and replace,long
lifetime,material can be recycled.

Temporary Bridges, Emergency Bridges and Fixed Bridges.Using the bridge equipment, the suspension bridges of varied span
can be erected.The bridge has the advantages of few components, light weight and
low cost.Bailey Bridge requires no special tools or heavy equipment for
construction, the bridge elementsare small enough to be carried in , and the bridge is strong enough
to carry . It is considered a great example of military
engineering.

The compact 200 panel bridge: The compact 200 panel bridge is
similar to the compact 100 panelbridge from their appearance. The difference is its increased panel
height to 2.134m. It employed the method of alternating joints
between Reinforcement Chords and the joints between panels. This
method can decrease inelastic deformation caused by the oversized
pinholes.Pre-arch method is used to additionally cut down mid-span and
vertical deflection to a larger degree.Bolt-connected components use the orienting sleeve- fixing method
to increase accuracy of connections. Shear is created in orienting
sleeves and tension is developed in bolts, which increase the usage
life of the bolts and ensure the safety of panel bridges. Wind
resistant brace is made to be composite type and is connected to
transom/girders to improve overall stability of panel bridges.
